We consider two ascending auctions for multiple objects: the SEAMO (simultaneous English auction for multiple objects … sequence of sealed-bid auctions. Then, we prove that many of the (unwanted) collusive or signaling equilibria studied in the … equilibria based on retaliatory strategies do exist in both auctions. …

The popularity of open ascending auctions is often attributed to the fact that openly observable bidding allows to … activate revenue enhancing biases. In an experiment, we compare three auctions that differ in how much information is revealed …

We consider two ascending auctions for multiple objects, namely, an English and a Japanese auction, and derive a … consists of a finite sequence of sealed-bid auctions. Thus an equilibrium of a continuous time game is derived by means of …

This study provides new identification and estimation results for ascending (traditional English or online) auctions …

We infer risk attitudes using distributions of … transaction prices and participation decisions in ascending auctions with entry costs. Nonparametric tests are proposed for two … identification of risk attitudes in ascending auctions with selective entry, where bidders receive entry-stage signals correlated …

We examine a model in which multiple buyers with single-unit demand are faced with an infinite sequence of auctions … an efficient and fully revealing equilibrium for the game in which the objects are sold via ascending auctions. We show …
